Send it to a GOOD Riflesmith/Machinist. The ejector slot can be done easily and the bolt face is redone so that the hole is invisible for the old ejector and the claw is remachined with judicious tig work thrown in. As I said, it takes a good craftsman to do this and I would have done this a year ago but family problems popped up. Any pushfeed can be converted with the proper work.
